CAR-ROOF.

Specification of Letters Patent.

'Application filed October 26, 1918. Serial N o. 259,771.

To all whom t may concern:

Be it known that I, WALTR P. MURPHY, a citizen of the United States, and a resident of the city of New York, in thev county of New York and State of New York, have invented a new and useful Improvement in Car-Roofs, of which thev following isa specication.

This invention relates to improvements in car roofs of the type,l wherein the metal roof sheets extend from eaves to eaves and are supported on a skeleton framework.

My invention relates to the means for fastening the seam covers and the'means for the attachment thereof to the carline. One of the principal objects of the invention is to provide means for fastening the seam cover directly to the carline so as to move therewith. Another object is to eliminate the hood casting commonly used in connection with this type of roof and thereby reduce the overall dimension of the roof.

A further object is to construct a roofv wherein the roof sheets` are free to move independently of each other and of the carlines and seam covers, within certain limits. A still further object isto prevent'any water that may leak around the securingl bolts from entering the car. Another object is to rigidly secure the seam cover to the carline whereby the seam cover is supported at afixed distance from the roof sheets thereby preventing the same from bearing on the roof sheet with any great force, and to attain further advantages hereinafter set forth.V

My invention consists in the parts and in the combinations and arrangements yof parts hereinafter described and claimed.l l

. In the accompanying drawings, wherein like reference numerals refer to like parts wherever they occur,

Figure 1 is a side elevation of an eaves portion of a car roof embodying my invention;

Fig. 2 is a vertical section o n the line 2-2 in Fig. 1, a' portion of the seam cover being broken away; l

Fig. 3 is a vertical cross-section through the roof the-region of the securing bolt on the line 3 3 in Fig. 2;

Fig. 4 is a vertical section taken on the line Ll--'f in Fig. 1;

Fig. 5 is a perspectiveview of the threaded saddle member;

1 Illg. 6 is a perspective view of the bolt oc l; j

Fig. 7 is a perspective view of the sheet metal apron;

Fig. 8 is a cross-section through the-seam showing the cut-away top portion of the seam; and

Fig. 9 is a cross-section throughy the roof similar to Fig. 3 showing a modified form of bolt lock and apron member.

Referring to the drawings, the invention is shown applied to a car comprising Z-bar side plates 9. Each Z-bar side plate is positioned with its web vertical and with its top flange facing in. The carline 10 extends from side plate to side plate. The end portions of the carline rest on the top flanges of the side plates to which they are riveted or otherwise secured. The carline 10 is substantially T-shaped in cross-section with its web portion 11 uppermost. A wooden fascia-board 12 is bolted to the vertical web of the side plate 9. The roof sheets 13 extend from eaves to eaves with their end portions resting on the top surface of the fascia and have end flanges 14 turned down into a rabbet 15 in the fascia board 12. Y The side margins of the sheets are bent upward in aninverted U-shaped flange 16, the ianges of one sheet overlapping the anges of the adjacent sheet, thus` forming upstanding hollow seams. The overlapped flanges 16, which form the hollow seams, extend from eaves to eaves and'straddle the vertical web 11 of the carline 10. A seam cover 17 of inverted channel-shape in cross-section having outwardly extending base flanges 18 is arranged over the hollow seams of the roof sheets. The base flanges practically touch the body portion of the adjacent sheets, but preferably mounted so as not to be clamped thereon. This seam cover'straddle's the roof sheet seams, its inside measurement being greater than the width of the seam so as to allow the sheets lto move endwise of the car. The ends of the seam cover are turned down at the eaves, the down-turned portions 19 closing the end ofthe seam cover and thereby preventing water from. entering the car.

The top portions' of the overlapped anges, which form the hollow seams, are cut away (as indicated at 20) at a suitable distance from each end of the sheets so as to permit the seam cover to be secured directly to the carline independent of the sheets. The

seam cover is secured to the web of the carline at each endby means of boltsA 21 inserted in T-slots 21e formed inthey top edges of the web of the carline and conforming in shape bolt. Each one of'the bolts 21 is held in position web by means of a channel-shapedl bolt lock 22. The bolt-lock straddlesthetopof the;

margins with downwardly and outwardly inclinedfdrip yflanges 24. A saddle member 251' isv` threaded i on' the vbolt sov` as to screwy down on the apron and clamp the apron and theboltLlock .securely in position on lthel web ofthecarline4 These saddle members act as supports for'the seam covers :and have their top'dportions-shaped to litthe under side of the top portion ofthe seam covers. The top surfacefof each" saddle member is provided with a groove `2t` eXtending v'crosswise Where the-bolt extendsthrough the vthreaded hole inthe same. member isprovidedi-with grooves 27 Aon each side justoutsidev of the downwardly inclined langes'of the` apron. The boltrv 21 passes through'an openingin the seam cover and is provided with anut 28 ion its apron and Nvhichis screwed do'wn'tightly on a washer 29.1 thus .holdingf'theseam cover in position.

Anzy'waterf-which may kleakf'in around the bolt hole. inthe seam` coverX willbe caught inthe groove 26irr the top faceof the saddle membery and conducted to its Iside' edges due toAA the -ioval shape of the -top'surfacerofthe saddle washer; Thefwater is preventedfrom travel-ing back'on the under side of the sa'ddlefwasher andlreaching the carliney web byfth'e grooves27 cut in the'under side of thefsaddlefcasting. This arrangementcauses tli'e"watervv to fall'on theinclined drip flanges 24v-of theapron 23 thereby causing the iwater tobe deflected. onto the body* portion of thersheets'on'each side of thefca-rlines. The cutting-eawayfofthe top` portion of the hol-v low seamA atA the eavesfend'of the sheetsto accommodatethe members for' securing the endiof the-seam'` cover to the carline permits th'elseamA cover to move') with the carline without; disturbing .the sheets" This ar-r rangement also" permits-iy movement ofthe sheets fcrosswisef Aor lengthwiserofithe car indep'endentlyr'offthecarlinet and seam cover.

A: combined bolt lock" and4 apron member iseshownein'Fzig. 91of"the drawing. The bolt locl 3Qfslown: this @ligure/s straddlesethe and size to the shank and head of thev in its respective slot in the carliney The underside ofthe saddle top of.` the carline web in a manner similar to the bolt lock22. The top portionof the bolt lock 30 isprovidedA on eachside with drip i'anges '31 which are curvedoutwardly anddownwardly so as to overhang the adj a` cent cut-away portions of the roof sheet flanges. The drip flanges y31 of the bolt lock 30'y are similar to the drip flanges 23 offthe apron Ymember:22::and cause any water falling thereon to be deflected onto the body portion of the sheetswvhen the sheetsare` in an -extreme Y position.
